I've had these growing in my garden for many years and despite my best efforts I have been unable to identify them. They are about 750mm tall and when young the stems have a reddish hue. I would be very grateful for any suggestions.
I could be way out but are they verbena? If so you would have had an abundance of flowers each year - I have red and white and they don't need to be told twice to get flowering. I've googled to hopefully find confirmation and this is the BBC plant profile:
It's not often I'm right but I could be wrong again
I think it a spurge a wild type of euphorbia
Caper Spurge, I think. Not to be confused with capers - these are poisonous.
Thank you so much for the replies. It 's definately Caper Spurge - I just had a look on Google. I should have posted a thread years ago, it's been driving me nuts.
Definitely caper spurge - if you're going to pull them up wear gloves and long sleeves - if you get the sap on your skin, especially on a sunny day, you'll get huge painful red wheals across your skin - I was quite poorly when as a child I decided to clear an overgrown part of the garden on a very sunny day.
On the plus side - they're supposed to deter moles. No idea if there's any evidence for it.
